The Capability of Harpacticoid Copepods to Ingest Bacteria as Food

Farzana Yasmeen


Harpacticoid copepods are known to feed on detritus and bacteria. An attempt was made to assess the same for a harpacticoid species, Cletocamptus albuquerquensis from Puzhal Lake, Chennai. The mono bacterial culture from the same habitat was isolated, sub-cultured and used as the feed under limited conditions. The results show a reduction in the bacterial cell count as the time of interaction with the harpacticoid increases. Further, spread plate technique of the sample at the end of every hour, confirms the decrease in bacterial cell count. Hence it is confirmed that the specific Gram-negative bacteria used in the present study are fed by the harpacticoid species.
